Abstract: A scroll compressor includes a main housing. A driving part configured to generate torque and a compression part driven by the driving part are accommodated in the main housing. The compression part includes a fixed scroll and an orbiting scroll that engages with the fixed scroll to form a compression chamber in which a refrigerant is compressed. The torque of the driving part is transmitted to the compression part by a driving shaft. The driving shaft is rotatably supported by a main bearing positioned in a low pressure region adjacent to the driving part. Accordingly, since the main bearing is disposed in a low pressure region, a load applied to the main bearing may be decreased.
